LOOK-SHUTTLE.

Specification of Letters Patent.

Patented Sept. 3, 1918.

Application filed February 6, 1.418. Serial No. 215,585. 1

It consists also in providing the shuttle with novel means for locking said bar in position.

It consists also of a device on said guarding bar for running the yarn or thread true to the threading passage in the nose of the shuttle.

The invention is satisfactorily illustrated in the accompanying drawings, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limitedto the specific details shown and described, as long as they are within the spirit or scope of the claims.

Figure 1 represents a plan view of a shuttle embodying my invention. I

Figs. 2 and 3 represent longitudinal sections respectively of opposite end portions of the shuttle on an enlarged scale.

Fig. 4 represents a transverse section'on line 4:4 Fig. 3.

Fig. 5 represents a longitudinal section of a portion on line 5-5 Fig. 4.

Fig. 6 represents a transverse section of a portion on line 6-6 Fig. 3.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawin 1 designates the body of the shuttle, and 2 designates the bobbin therein said bobbin being mounted on the rod or spindle 3, as

usual. The base of the bobbin has a portion cut away as at 4, and has in its side adj acent to said portion the transversely-extending groove or recess 5. 6 designates a plate which is mounted by the rod 7 as an axis on the body adjacent to the base of the bobbin, it being formed of metal preferably steel, and is adapted to extend over the bobbin with the yarn or thread thereon as a cover and guard therefor, and also to retain the bobbin properly in the body ofthe shuttle, sa d plate being somewhat bowed and resilient in its nature -so as to. be held firmly in position when it is closed, and to spring out therefrom when released, as will be hereinafter again referred to.

y In order to retain the bobbin in position, the plate 6 is formed at its axial end with the tongue 8 which is an integral portion of the plate 6, it bein noticed that said plate is continued towarf its axial end where it is formed with the sleeve 9 in which is re-' ceived" the axial rod 7, and then bent back on tself as at 10 which is adapted to be pressed inwardly by the contiguous portion. 11 of the plate, the terminal of said bent back portion 10 opposite to the sleeve 9 havin thereon the inturned tongue 8 which exten s at an angle from said terminal and is adapted when the plate is lowered to enter the recess.

5 in the base of the bobbin, thus causing the oobbin to be interlocked by said tongue, and consequently by the plate 6, whereby it is held in position in the body of the shuttle 7 in a firm, simple and eflicient manner, it

being seen that when the plate is raised said tongue emerges fromthe recess 5, and so the bobbin is unlocked and may be removed from the body of the shuttle.

position, the termina thereof opposite to the sleeve 9 has thereon the outturned lipnose of the body of the s uttle, said latch having therein in the direction of its length I the slot 17 through which the yarn or thread runs from the bobbin to said passage, said slot being open at the top or the free end of the latch, whereby when the yarn or thread is presented to said slot it may be pressed down thereinto so as to enter the same when it is guided to said threading passage 16 and so entered in the latter.

In order to hold the latch engaged -,w ith .the lip 12 it is engaged by one end of thecoil spring 18 and so ressed against sai In order to lock the plate 6 when in closed lip, theother end of said spring .bein held.

in the adjacent portion of the body, it eing guided and retained in place by the stud 19 which is secured to the latch and enters cover the bobbin.

On the inner side of the plate 6 and firmly secured thereto is the leg which enters the body of the shuttle adjacent to the latch Hand head end of the bobbin it being of open form, staple-like or U-shape, as an open eye preferably of elongated form. through which the-yarn or thread passes freely from the bobbin to the slot 17 in the latch 14, and so centering the yarn or thread true to said slot and consequently to the threading passage, thus effectively preventing what is known as ballooning of the yarn or thread.

It will be noticed, referring more particularly to Fig. 4, that the slot or passage 17 in the latch 14 is narrow in width sulfficient to permit in weaving the yarn or thread to run freely therethrough from the leg or eye 20, but should there be a knot in, the yarn or thread, it will be caught or trapped on the walls of said slot so that the yarn or thread in its draft will break be tween said walls and the threading passage retaining the knot within the shuttle and preventing it from bein woven.

Having thus describe my invention what I claim as new and desire to secure by Let ters Patent, is

1. In a shuttle, a guard and a retainer for a bobbin composed of a plate, a sleeve on the latter by which said plate is mounted on the body of the shuttle, said plate having a portion of itself bent back on the plate from the axis of the latter, and a tongue on the terminal of said portion, said tongue being adapted to engage the bobbin to-interlock the same in the shuttle.

2. A shuttle having a guard for the bob bin and a retainer therefor in the body of the shuttle composed of a plate adapted to be pivotally mounted on said body, a tongue member on said plate near the pivotal end to thereof, and a bobbin having therein a transversely extended groove in which said tongue member is adapted to be seated.

3. In a shuttle, a guard. and a retainer for a bobbin in the shuttle composed of a swinging plate, a lip on the free end of the latter, and a latch on the body of the shuttle having a hook-like member adapted to engage said lip, said latch having therein a longitudinally extending slot which is open at its free end and adapted to be in communication with the threading passage in the body of the shuttle,

i. In a shuttle, a guard and a retainer for the bobbin comprising a pivoted plate, and a tongue member thereon disposed beneath the bod portion of said plate near the piv otal en thereof and extending from the under face of the plate with its free end engageable in a recess in the side of the bobbin and engageable therewith.

5. In a shuttle, a retainer for a bobbin composed of a latch-like plate mounted at I one end of the body of the shuttle, a latchlike device mounted on the opposite end of said bodyadjacent to the threading passage of the latter, said plate having therein a longitudinally extending slot which is open at the free end of the plate and adapted to be in communication with said threading pas- 8O sage.
